Ingredients
2 large onions (yellow or sweet onions work best)
2 tablespoons olive oil (or butter, if preferred)
1 teaspoon salt
1 tablespoon balsamic vinegar (optional for added depth)
Instructions
-
Prepare the Onions: Peel and cut off the ends of the onions. Slice them thinly into half-moon shapes.
-
Heat the Skillet: Place a heavy skillet over medium-low heat and add olive oil (or butter). Allow it to warm until shimmering.
-
Cook the Onions: Add the sliced onions to the skillet, spreading them evenly. Sprinkle with salt to help draw out moisture.
-
Sauté the Onions: Stir the onions frequently, cooking for about 10 minutes until they soften and become translucent.
-
Caramelize the Onions: Reduce the heat to low and continue cooking, stirring every few minutes, until the onions turn a deep amber color and become soft and jam-like in texture. This should take about 30 minutes.
-
Optional Balsamic Vinegar: Drizzle balsamic vinegar over the onions (if using), and stir well. Cook for an additional 2-3 minutes until the onions are glossy and fragrant.
-
Cool and Serve: Remove from heat and allow the caramelized onions to cool slightly before serving.
Notes
- Herbs: Add fresh herbs like thyme, rosemary, or bay leaves while cooking for extra flavor.
- Spicy: Add a pinch of red pepper flakes for a mild spicy kick.
- Vegan Option: Use olive oil instead of butter for a completely vegan version.
- Sweetness Level: Add a touch of sugar if you prefer extra sweetness, although the onions will naturally caramelize to a sweet flavor without added sugar.
